@centrox,
Well we can agree to differ. Each of us brings our own 'context' to the question.
Only the questioner can decide which, if any, is useful.
At the risk of compounding my tangential thinking, this differential focus issue
is one basis of Derrida's point that context has a temporal aspect which cannot be recaptured. He clamed that 'meaning' shifts even when re-read by the author because the author has 'moved on'.
